I think I know what you mean, but, most of the time Goodness only knows when and what will happen next. Really, all I will go by is news and what management says, and act on what I think of it.
So, right now, I am keeping the stock and looking for the chance to get some more if it goes down further. Not going to try for the absolute bottom, that's impossible.
Usually when you see a drop in the market like we got to-day, there is more coming! Not always, though.
Cheers!
